Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a bracket device, and more
particularly, to a bracket device applicable to a rack system or a
slide rail assembly.
2. Description of the Prior Art
[0002] As shown in FIG. 1 and FIG. 2, in a rack system, a carried
object 102 (such as an electric device, a chassis or a drawer) can
be mounted to a rack (such as a post 108 of the rack) through a
bracket device 106 of a slide rail assembly 104. Specifically, the
carried object 102 can be pulled out of the rack to be located at
an extension position E through the slide rail assembly 104; or,
the carried object 102 can be pushed into the rack from the
extension position E to be located at a retracted position R.
[0003] As shown in FIG. 3, the bracket device 106 comprises a
mounting member 110 and a fastening member 112. The mounting member
110 is configured to be inserted into a mounting hole of the post
108. The fastening member 112 is configured to be located at a
locking position P1 or be moved away from the locking position P1.
Wherein, when the fastening member 112 is located at the locking
position P1, a fastening part 114 of the fastening member 112 is
configured to lock the post 108. For example, the fastening part
114 of the fastening member 112 is in front of the post 108 to
block the post 108. In such state, the mounting member 110 can be
prevented from detaching from the mounting hole of the post 108
along a direction D (such as a backward direction).
[0004] As shown in FIG. 4, sometimes an on-site staff needs to
perform shock test on the slide rail assembly 104 mounted to the
post 108 of the rack through the bracket device 106. If a shock
force is too large, the mounting member 110 might be slightly moved
backward from the mounting hole of the post 108 along the direction
D due to tolerances, such that the fastening part 114 of the
fastening member 112 is driven to hit the post 108 to further cause
the fastening member 112 to move away from the locking position P1
to be located at an unlocking position P2. In other words, the
fastening part 114 of the fastening member 112 no longer locks the
post 108. In such state, the slide rail assembly 104 might fall
from the post 108 so as to cause damages on the carried object 102
or hurt people. As such, the slide rail assembly 104 has some
safety concerns. On the other hand, when the carried object 102 is
pushed by a strong force along the direction D to move from the
extension position E to the retracted position R, an ear part 103
of the carried object 102 might strongly hit the mounting member
110. In such state, the fastening member 112 might be shocked to
move away from the locking position P1 to be located at the
unlocking position P2, which causes the same aforementioned
problems. Therefore, it is important to develop a reliable
product.

[0037] As shown in FIG. 8, the first post 22a has a plurality of
mounting holes 56. On the other hand, the first rail 30 is
configured to be mounted to the first post 22a of the rack 22
through the first bracket device 26. Furthermore, the first vertex
47 of the mounting member 40 of the first bracket device 26 exceeds
one side of the first post 22a of the rack 22. For example, the
mounting member 40 of the first bracket device 26 penetrates
through the mounting hole 56 of the first post 22a, such that the
first vertex 47 of the mounting member 40 is moved from a rear side
of the first post 22a to a front side of the first post 22a.
Wherein, when the fastening member 42 of the first bracket device
26 is located at the locking position P1, the supporting part 52 is
adjacent to the mounting member 40, and the second vertex 54 of the
supporting part and the first vertex 47 of the mounting member 40
are substantially located at a same longitudinal position along the
longitudinal direction. In a first embodiment of the present
invention, the second vertex 54 of the supporting part 52 and the
first vertex 47 of the mounting member 40 are actually located at
the same longitudinal position along the longitudinal direction.
Preferably, the fastening member 42 further comprises a
longitudinal part 58, a transverse part 60 and an operating part
62. The longitudinal part 58 is connected between the transverse
part 60 and the operating part 62. The transverse part 60 is bent
relative to the longitudinal part 58. Preferably, the supporting
part 52 is extended a first predetermined distance X1 from the
transverse part 60 along the longitudinal direction. The fastening
member 42 further comprises an extension wall 64 extended a second
predetermined distance X2 from the transverse part 60 along the
longitudinal direction, and the second predetermined distance X2 is
smaller than the first predetermined distance X1. The extension
wall 64 is connected to the supporting part 52 in order to
reinforce structural strength of the supporting part 52.
[0038] As shown in FIG. 9, the fastening member 42 is configured to
be moved away from the locking position P1 to be located at an
unlocking position P2. Preferably, a user can operate the operating
part 62 to move the fastening member 42 from the locking position
P1 to the unlocking position P2. Wherein, when the fastening member
42 is located at the unlocking position P2, the supporting part 52
is away from the mounting member 40.
[0039] Moreover, when the fastening member 42 is located at the
locking position P1, the fastening member 42 (or the transverse
part 60 of the fastening member 42) is configured to lock the first
post 22a (as shown in FIG. 8). When the fastening member 42 is
located at the unlocking position P2, the fastening member 42 (or
the transverse part 60 of the fastening member 42) no longer locks
the first post 22a (as shown in FIG. 9), such that the mounting
member 40 can be detached from the mounting hole 56 of the first
post 22a.
[0040] As shown in FIG. 10 and FIG. 11, the slide rail assembly 24
can be correspondingly mounted to the first post 22a and the second
post 22b through the first bracket device 26 and the second bracket
device 28. Wherein, the fastening member 42 is located at the
locking position P1, and the fastening member 42 (or the transverse
part 60 of the fastening member 42) is configured to lock the first
post 22a (please also refer to FIG. 12). Furthermore, the carried
object 23 is movable along the longitudinal direction through the
slide rail assembly 24. In the present embodiment, the carried
object 23 can be moved along the longitudinal direction relative to
the first rail 30 through the second rail 32 from a predetermined
position R to an extension position E; or, the carried object 23
can be moved from the extension position E to the predetermined
position R. Wherein, the predetermined position R can be a
retracted position.
[0041] As shown in FIG. 12, when the fastening member 42 is located
at the locking position P1 and the carried object 23 is located at
the predetermined position R, the second vertex 54 of the
supporting part 52 of the fastening member 42 is configured to abut
against the ear part 23b of the carried object 23. Preferably, when
the fastening member 42 is located at the locking position P1, the
transverse part 60 of the fastening member 42 is close to (or
adjacent to) a surface S of the first post 22a.
[0042] In addition, when the carried object 23 is pushed by a
strong force to move from the extension position E to the
predetermined position R along a direction D, the ear part 23b of
the carried object 23 might strongly hit the second vertex 54 of
the supporting part 52 of the fastening member 42, or the ear part
23b of the carried object 23 might strongly hit the first vertex 47
of the mounting member 40. In such state, the slide rail assembly
24 is slightly moved backward along the direction D. Wherein, since
the transverse part 60 of the fastening member 42 at the locking
position P1 is close to (or adjacent to) the surface S of the first
post 22a, the transverse part 60 of the fastening member 42 is
configured to abut against the surface S in response to the slide
rail assembly 24 slightly moving backward along the direction D, in
order to prevent the fastening member 42 from moving away from the
locking position P1 caused by shocks of impact. Therefore,
reliability and safety of mounting the slide rail assembly 24 or
the first bracket device 26 to the first post 22a of the rack 22
can be ensured.
[0043] Preferably, when the carried object 23 is located at the
predetermined position R relative to the first rail 30 through the
second rail 32, at least one portion (such as a front rail section)
of the second rail 32 is adjacent to and corresponding to a lateral
side of the longitudinal part 58 of the fastening member 42, so as
to block the fastening member 42 for preventing the fastening
member 42 from moving away from the locking position P1 along a
rotational direction.
[0044] FIG. 13 is a diagram showing a first bracket device 200
according to a second embodiment of the present invention.
Specifically, a second vertex 204 of a supporting part 202 and the
first vertex 47 of the mounting member 40 are substantially located
at the same longitudinal position along the longitudinal direction.
However, in the second embodiment, the longitudinal position of the
second vertex 204 of the supporting part 202 is slightly behind the
longitudinal position of the first vertex 47 of the mounting member
40 due to tolerance. When a fastening member 201 is located at the
locking position P1 and the carried object 23 is moved from the
extension position E to the predetermined position R along the
direction D to strongly hit the first vertex 47 of the mounting
member 40, the slide rail assembly 24 is slightly moved backward
along the direction D. Since a transverse part 206 of the fastening
member 201 at the locking position P1 is adjacent to the surface S
of the first post 22a, the transverse part 206 of the fastening
member 201 is configured to abut against the surface S in response
to the slide rail assembly 24 slightly moving backward along the
direction D. Moreover, the ear part 23b of the carried object 23
might be supported by or abut against the supporting part 202 due
to impact. Therefore, the fastening member 201 is prevented from
moving away from the locking position P1.
[0045] FIG. 14 is a diagram showing a first bracket device 300
according to a third embodiment of the present invention.
Specifically, a second vertex 304 of a supporting part 302 and the
first vertex 47 of the mounting member 40 are substantially located
at the same longitudinal position along the longitudinal direction.
However, in the third embodiment, the longitudinal position of the
second vertex 304 of the supporting part 302 is slightly in front
of the longitudinal position of the first vertex 47 of the mounting
member 40 due to tolerance. When a fastening member 301 is located
at the locking position P1 and the carried object 23 is moved from
the extension position E to the predetermined position R along the
direction D, the ear part 23b of the carried object 23 is supported
by or abuts against the second vertex 304 of the supporting part
302 of the fastening member 301. Furthermore, when the carried
object 23 strongly hits the second vertex 304 of the supporting
part 302 along the direction D, the fastening member 301 is
prevented from moving away from the locking position P1 since a
transverse part 306 of the fastening member 301 is adjacent to the
surface S of the first post 22a.
[0046] Therefore, the rack system of the present invention is
characterized in that:
[0047] 1. When the fastening member (42, 201, 301) is located at
the locking position P1, the second vertex (54, 204, 304) of the
supporting part (52, 202, 302) and the first vertex 47 of the
mounting member 40 are substantially located at the same
longitudinal position along the longitudinal direction. The second
vertex (54, 204, 304) is configured to abut against or support the
ear part 23b of the carried object 23.
[0048] 2. Since the transverse part (60, 206, 306) of the fastening
member (42, 201, 301) is adjacent to the surface S of the first
post 22a, the transverse part (60, 206, 306) of the fastening
member (42, 201, 301) is configured to abut against the surface S
in response to an external force or an impact force, in order to
prevent the fastening member (42, 201, 301) from moving away from
the locking position P1 due to shocks of impact, such that the
fastening member (42, 201, 301) cannot be freely moved away from
the locking position P1 to the unlocking position P2 by the
external force. Therefore, reliability and safety of mounting the
slide rail assembly 24 or the first bracket device (26, 200, 300)
to the first post 22a of the rack 22 can be ensured.
[0049] 3. When the carried object 23 is located at the
predetermined position R relative to the first rail 30 through the
second rail 32, at least one portion of the second rail 32 is
adjacent to the lateral side of the longitudinal part 58 of the
fastening member (42, 201, 301), so as to prevent the fastening
member (42, 201, 301) from moving away from the locking position
P1.
[0050] Those skilled in the art will readily observe that numerous
modifications and alterations of the device and method may be made
while retaining the teachings of the invention. Accordingly, the
above disclosure should be construed as limited only by the metes
and bounds of the appended claims.
